Production habit: Breeding with seeds. Picking ripe fruits, rubbing off pulp, and taking out seeds; Before and after the light snow festival, layer with wet sand, sow in the spring of the following year, or directly sow in the field from the end of 1 1 month to the beginning of1February; Before overwintering, it is watered for a second time, and seedlings can emerge in the next spring.

I like fertile and deep soil, but I have a certain tolerance for barren soil, moderately alkaline soil and calcareous soil. Strong resistance to sulfur dioxide.
